Exterior Waterproofing in Philadelphia, PA

When water is reaching your foundation from the outside — through poor grading, a failed membrane, or saturated soil — the fix belongs outside too, not just inside masking the symptom.

Why Choose Our Specialized Exterior Waterproofing in Philadelphia, PA

Four commitments that separate a properly trained exterior waterproofing crew from a generalist showing up with a truck and a hope.

Professional Exterior Waterproofing technician working in Philadelphia, PA
01

Excavation & Membrane Certification

Crews are trained in proper excavation depth, membrane application technique, and footing drain installation specific to exterior waterproofing systems.

02

Local Dispatch for Grading Assessments

Active water intrusion visible from outside — pooling against the foundation, saturated soil — moves to priority scheduling.

03

Itemized Excavation Pricing

Pricing accounts for landscaping restoration where excavation disturbs existing beds or hardscape.

04

Commercial-Grade Membrane Systems

Footing drains are set in washed gravel and wrapped in filter fabric to resist silt clogging over the system's service life.

Comprehensive Exterior Waterproofing Service Solutions

Each service below is scoped specifically to exterior waterproofing, not a generic waterproofing menu with the name swapped in.

01

Foundation Excavation & Membrane Application

Drainage board goes over the membrane to create a channel for water to travel down to the footing drain instead of pressing against the wall. This is the most thorough exterior fix available and typically carries the longest service life of any waterproofing method.

02

Footing Drain Installation & Repair

Older homes often have footing drains that have silted in or collapsed over decades — we assess existing drain condition and replace where compromised.

03

Grading & Drainage Correction

Soil that slopes toward the foundation instead of away from it sends every rainfall straight at your basement wall, regardless of how good the membrane below is.

04

Window Well Drainage Systems

Window wells without proper drainage collect and hold water against a vulnerable point in the foundation wall — often the source of a leak that seemed to come from nowhere.

05

Exterior Crack & Joint Sealing

Cracks and cold joints exposed during excavation get treated directly at the source, from the outside, before the membrane goes over them.
